Yes I did try turning down the NB multi but was still unable to boot at 260 HTT. Right now Im running dual orthos at 246x13 with SB Clock Spread Spectrum disabled. I attempted to run dual orthos while at work at 249 and it crashed tho Im not sure at what time it happend. Same goes for 246x13 overnight. Im hoping that stupid setting is the culprit because Ive been able to play COD4 and Stalker just fine at these settings.

What do you guys use for testing stability in Vista 32/64? Could there be a chance that orthos just isnt the way to go with vista?
